The annual military parade in Tehran on 21 September included a Khorramshahr ballistic missile fitted with a notably smaller re-entry vehicle (RV) that would give it a longer range.
Unveiled in the September 2017 parade and widely believed to be based on the North Korean BM-25, the Khorramshahr reportedly has a range of 2,000 km with a warhead weighing 1,800 kg, giving it a far heavier payload capability over that distance than Iran's Shahab-3 family of missiles.
The development of a smaller RV for the Khorramshahr was noted in March, when France, Germany, and the United Kingdom sent a joint letter to the Security Council saying one had been publicly displayed during the Ten Days of Dawn event in Tehran on 4 February. No images showing this variant appear to have been released at that time.
